Insecure women don't have an easy life, especially when they are in a relationship, and it's even worse for their men.
Insecurity may seem cute and nice on rare occasions, but usually, it's a just annoying trait that can make the most interested man cool down. These things will appall most men, and they all come out of insecurity.
Going through his cell phone
His phone is his phone, just like his social networks are his social networks and if at some point you think it's a good idea to take a look at it, think again. Men can't stand women who go through their phone - not necessarily because they have something to hide but because it is an invasion of privacy.
Jealousy can be cute in small doses, but jealous women rarely know how to distribute their jealousy. Jealous women become possessive and paranoid, but these are not advantages in the men's eyes.
Intolerance towards other women
Each of us has that one woman that unbelievably gets on our nerves, even if it is not completely justified, but a woman who is allergic to all other women around her man generally becomes very unattractive to a man.
Women who are sure of themselves are not afraid of other women, nor they hate them for no reason.
